摘要

A computer acquires the aspect ratio of an image and the aspect ratio of the display of a monitor and compares the aspect ratios with each other. With the aspect ratio of the monitor display taken as a reference, the computer determines which one of the vertical length and the horizontal length of the image is longer. The computer sets the magnification of the image based on the decision result in such a way that one of the vertical size and the horizontal size of the image matches with or becomes slightly smaller than the frame of the monitor display, and enlarges or reduces the image. The computer outputs data of the size-adjusted image to a projector.
